COKE-DRAWI No. 812,364. Specification of NG MA'CHINE.

Letters Patent, Patented Feb. 13, 1906;

Application filed November 1,1905. Serial No. 235,441.

To all whom it may concern/.-

Be it known that LDANIELABNE RAMAGE, residing at Percy, in the county of Fayette and State of Pennsylvania, have invented a new and Improved Coke Drawing Machine, of which the following isea specification.

This invention relates to means for drawing or pulling coke from coke-ovens; and it comprehends generally a carriage or frame mounted on truck-wheels, a cylinder axially supported on the frame to turn thereon in a 5 horizontal plane and carrying fluid-pressure feed mechanism adapted-to be led into the opposite ends of the cylinder, and a piston within .the cylinder whose rod forms a supporting means for detachably receiving the, drawing or puller devices that go into the oven and scrape out the cokev In its more subordinate features my'invention consists in certain details of construction and peculiarcombination of parts, all of which will be hereinafter l'ully described, pointed out in the appended claims, and illustrated in the accompanying drawings, in which Figure 1 is a perspective View of myinvention, illustrating the manner in which it is used. Fig. 2 is a side elevation thereof. Fig. 3 is a plan view thereof, the fluid-controlling valve being shown in horizontal section. Fig. 4 is a transverse section of the same on the line 4 4 of Fig. 3. Fig. 5 is a detail perspective View, partly in section, ,of a part of the rib portion of the drawing or scaping devi'ce.

lower end of which is Fig. 6 is an enlarged section of the valve on the line 5 5 of Fig. 4. I

In carrying out my invention I providea wheel-truck frame A, upon which is mounted a longitudinal cylindrical body 0, having sufficient length to allow enough piston thrust to admit of a proper movement oi 'the drawing or scraping device, presently described, within the oven.

The cylinder C, which, it will be noticed, has no steam chest, is provided centrally with a suitable annular seat portion 0, the projected laterally, as at c c, to provide for a firm bearing for engaging the turn-table to properly sustain the cylinder at either of'its horizontally-adjusted positions, and to facilitate the adjustments of the cylinder the laterally-projected portions of the bearing member may have and preferably are rovided with roller-bearings c, that engage tlie depressed seat or way on the top of the turn-table, and to provide for a simple,

economical, and ,easilymanipulated meansfor turning the cylinder to the desired posil tions with respect to the oven-doors the bearj ing member has a central socket 0 that engages the shouldered end of a stud-axle g", which projects centrally from the tablevor frame G. i

t The stud-axle g has a stationary horizontally-disposed gear 9 with which a pinion g l on the lower end of a hand-wheel shaft 0 enl gages, and thesaid shaft 0 is sustained in a vertical bearing portion c on the annular bearing member,.as clearly shown in Fig. 4, by reference to which it will be also seen that the said gear and pinion devices are so disposed that by simply manipulating the handwheel the cylinder can be turned on the axlestud to the horizontal positions desired with respectto the position of the truck-frame and ,the oven-door. v i l The annular bearing-frame'at the top and centrally over the cylinder C detachably rel ceives a four-wayvalve mechanism which comprises the chest at, having a pendent member a to detachably engage the flanges on the annular bearing member, and is formed with a pair of oppositely-dispose l ports a a", that connect with the long pipes E E, one ol which discharges through ,the permanent head oi the cylinder, while the other discharges throughthe removable caphead C of the cylinder (I; which cap-head is provided witha long stulling-box or gland X. through which the rod d, attached to the piston D, plays, as clearly shown in Fig. 2. The

a and outlet a", which in practice has a lexible feed-pipe section 5, that joins with the the direction of feed of said fluid through the valve-chest is regulated by the valve K, pro vided on diametrically opposite sides with channels orports 7r 7c, adapted when the valve K is adjusted through the inediuni oi" the hand-lever L to the position shown in Fig. 6 to open up a direct communication from the feed-pipeto the pipe-section E, that discharges into the cylinder (1, and when ad justed, as shown in dotted. lines, to close oil the pipe E from the fluid-inlet and bring it in line with the exhaust a and at the same time bring the pipe E into steam-pi e, and when centrally adjusted it cuts out both of the leads to the cylinder.

valve-chest a is also provided with an inlet source of the actuating fluid, steam, or air, and

ion

communication with the Upon the'forward end of the shaft is 'de' 1 taohabl'y mounted to move in a horizontal plane a scraper'or' puller device whichcomav I space-ribs r and prises a cross-frame R, having a rear portion formed with a long socket r to receive the front end of the piston rod, which is firmly held therein by the lockpin r; "The'scraper R consists of a solid plate whose rounded end is wedge-shaped and terminates with a shoulder-like portion that merges with a series of at the rear end on the opposite side of the solid plate are guide-rollers 2 2. adapted to engage. the sides of the oven, and thereby permit of sliding the scraper into and out of the oven. Between the ribs 1 is pivotally mounted a series of detents or fingers r, and the several fingers r are so mount ed upon a single cross-rod 1' that when the said fingers are at their normal position they are dropped baclcon thesolid bottom (see Figs. 1 and 2) in' such manner as to not interfere with the movement of the scraper in the coke mass; but when the said scraper-fingers are drawn up to a vertical position (see Fig. 5 and the dotted lines on Fig. 2) they form rake members for drawing the coke out of the oven-door as the scraper is pulled forward.

From the fore oing description, taken in connection with the accompanying drawings, it is believed the complete construction and operation of my invention will be readily understood. By reason of the simple arrangement of the several arts the operator can quickly setthe cylin er on the turn-table to suit the particular oven to be drawn,w .and;

l since the cylinder is sustained in the manner the shoulders of the stated the piston strain is evenly distributed therein, and no irregular or tensile strain is ap lied to the drawing device.

hen it is desired to'use a larger or smaller scraper drawing mechanism, it is only necessary to move the one in use b disconnecting the samefrom the front end 0 the piston-rod, which is done by simply removing the lock pin orboltbefore referred to. By forming the front end of the scraper-fingers in the nature of rongs and connecting the latch or rib memers in the manner shown it is obvious that rong' ends of the fingers will act as stops to hold the ribs or latches from being swung beyond a vertical plane, and, furthermore, since the shoulders on the fingers are inclined rearwardly and the ribs can never reach the full vertical position it follows that the. slightest pressure against them in forcing the fingers into the oven will cause. the said latches or ribs to assume a horizontal position and freely ride into thecoke mass within the coke-oven.

Having thus descr'bed my 1nvention,whati I claim, and desire cut, is'
